Aluminum/Copper heatsinks can be left as is or be taken apart and sorted into aluminum and #2 copper (possibly #1 if you have unsoldered pieces). You can use a propane torch to heat the metal and usually a tap will knock the different parts apart. Some may be more difficult and require some force to slide aluminum off of copper. **FAIR WARNING, the laptop ones with a flat copper tube can POP Forcefully when heated!** Either cut the tube to relieve the pressure or be very careful.
Second Set:
1-3) Remove the metal shields so we can see what's in them; as is low grade, potentially much better
4) Low grade
5) Low grade no reason to break that part off of the board --->4&5 take care when disassembling (especially older) monitors. Lots of potential bad stuff in there.
Third Set:
(Laughing at myself and not going to erase the above comments on 1-3 so you can see what I mean by potentially much higher) This picture is awful by the way, these grades are an at minimum but may even go up a grade if the focus was better.
1) High peripheral (shields go in steel)
2) Low peripheral (shields in steel)
3) Honestly I just normally throw these in low grade if they come loose from a board but might be midgrade with the shields off. (shields=steel)
